Properties
This system can accommodate up to 288 optic fibers.
The lightweight design adds less load to the tower and can span up to 1500m.
It has a strong anti-pull performance of more than 90KN.
The non-metallic structure provides good insulation and excellent lightning resistance.
The aramid yarns are equally distributed and have good production processes, resulting in excellent stress/strain performance.
It has excellent bullet-resistant performance.
It has excellent tracking-resistant performance.
The system can be installed without a power-off, and the normal transmission of the cable won't be influenced by power line faults.
